A real-time, high-accuracy, hardware-based integrated parameter estimator for deep space navigation and planetary radio science experiments

Liu, Wei; Wang, Zhen; Jian, Nianchuan +9 more

Real-time, high-accuracy frequency-phase estimation is the critical mission of Doppler tracking, which is a primary technique for deep space spacecraft navigation and planetary radio science experiments. Usually, the analog intermediate frequency signal is digitalized and converted to baseband by signal processing hardware platforms called digital…
